The Irony of it is that the Church HAS dogmatically defined heliocentrism (a fixed sun and moving earth) as formal heresy.

THE DOCTRINE OF GEOCENTRISM: St Clement of Alexandria demonstrated that the altar in the Jєωιѕн Tabernacle was “a symbol of the earth placed in the middle of the universe:” nothing more was needed; the geocentric theory was fully adopted by the Church and universally held to agree with the letter and spirit of Scripture. Wrought into this foundation, and based upon it, there was developed in the middle ages, mainly out of fragments of Chaldean and other early theories preserved in the Hebrew Scriptures, a new sacred system of astronomy, which became one of the great treasures of the universal Church – the last word of revelation. Three great men mainly reared this structure. First was the unknown who gave to the world the treatises ascribed to Dionysius the Areopagite. It was unhesitatingly believed that these were the work of St Paul’s Athenian convert, and therefore virtually of St Paul himself. Though now known to be spurious [sic], they were then considered a treasure of inspiration, and an emperor of the East sent them to an emperor of the West as the most worthy of gifts. In the ninth century they were widely circulated in Western Europe, and became a fruitful source of thought especially on the whole celestial hierarchy. Thus the old ideas of astronomy were vastly developed, and the heavenly hosts were classed and named in accordance with indications scattered through the sacred Scriptures.
